Description

一种储罐用的除桥装置A bridge removal device for storage tanks

技术领域Technical field

本申请涉及煤粉储存设备技术领域,具体地,涉及一种储罐用的除桥装置。The present application relates to the technical field of pulverized coal storage equipment, and specifically to a bridge removal device for storage tanks.

背景技术Background technique

其中,储存煤粉等粉体的储罐在卸料过程中,易出现粉体架桥,影响粉体卸料,从而影响系统整体运行稳定性。Among them, during the unloading process of storage tanks storing powders such as pulverized coal, powder bridging is prone to occur, which affects powder unloading and thus affects the overall operational stability of the system.

现有技术中粉煤锁斗出现架桥时一般的操作如下:先关闭粉煤锁斗与给料罐的平衡阀,以及关闭粉煤锁斗下料阀,再开启粉煤锁斗充气锥进气阀往上吹吹或者开启粉煤锁斗上部充压阀往下压。上述方案除桥效果不佳,无法松动锁斗中间段的粉体,从而降低除桥的效率,同时操作时会先暂停粉煤锁斗下料,影响粉煤输送系统正常运行。In the prior art, the general operation when bridging occurs in the pulverized coal lock hopper is as follows: first close the balance valve of the pulverized coal lock hopper and the feed tank, close the discharge valve of the pulverized coal lock hopper, and then open the inflatable cone in the pulverized coal lock hopper. Blow the air valve upward or open the pressure valve on the upper part of the pulverized coal lock hopper to press down. The above solution has poor bridge removal effect and cannot loosen the powder in the middle section of the lock hopper, thereby reducing the bridge removal efficiency. At the same time, the unloading of the pulverized coal lock hopper will be suspended during operation, affecting the normal operation of the pulverized coal conveying system.

综上所述,如何在不影响粉煤输送系统正常运行的前提下提高除架桥的效率是目前本领域技术人员亟待解决的问题。To sum up, how to improve the efficiency of bridge removal without affecting the normal operation of the pulverized coal conveying system is an urgent problem that needs to be solved by those skilled in the art.

上述的储罐在卸料过程中,易出现粉体架桥,从而把储罐的出口堵住,影响粉体卸料,进而影响系统整体运行稳定性,因此本申请为了解决该问题设计了除桥装置。During the unloading process of the above-mentioned storage tanks, powder bridging is prone to occur, thereby blocking the outlet of the storage tank, affecting the powder unloading, and thus affecting the overall operational stability of the system. Therefore, this application designed a removal method to solve this problem. bridge device.

除桥装置工作时,气体通过进气通道进入储罐内,便可松动储罐内的粉体,同时当除桥套筒组件上下移动时,进气通道也跟随上下移动,气体便可以通入储罐内的不同位置处,以松动位于储罐内不同高度位置的粉体,使得储罐内的架桥更容易下落。这样一来,该装置能够在不影响粉煤输送系统正常运行的前提下提高除架桥的效率。When the bridge removal device is working, the gas enters the storage tank through the air inlet channel, which can loosen the powder in the storage tank. At the same time, when the bridge removal sleeve assembly moves up and down, the air inlet channel also moves up and down, and the gas can be passed in. At different positions in the storage tank, the powder at different heights in the storage tank is loosened, making it easier for the bridge in the storage tank to fall. In this way, the device can improve the efficiency of bridge removal without affecting the normal operation of the pulverized coal conveying system.

在上述实施例的基础上,作为进一步的优选,除桥套筒组件包括外套筒2-2以及内套筒1-3。其中,外套筒2-2的一端设于储罐内,且沿储罐的轴向延伸至储罐的底部,具有多个连通储罐的第一通孔2-3;内套筒1-3的一端设于外套筒2-2内,且可沿外套筒2-2移动,具有多个连通外套筒2-2的第二通孔1-4,第一通孔2-3、第二通孔1-4以及内套筒1-3的内侧壁形成进气通道。Based on the above embodiment, as a further preference, the bridge removal sleeve assembly includes an outer sleeve 2-2 and an inner sleeve 1-3.

It has a plurality of second through holes 1-4 and first through holes 2-3 communicating with the outer sleeve 2-2. , the second through hole 1-4 and the inner wall of the inner sleeve 1-3 form an air inlet channel.

具体地,以附图1的方位为参考,外套筒2-2的一端固定安装于储罐内,而内套筒1-3的一端可相对储罐以及外套筒2-2上下移动,外套筒2-2以及内套筒1-3的底端均密闭设置。工作时,通过将内套筒1-3上的第二通孔1-4对准外套筒2-2上的第一通孔2-3设置,以将流入内套筒1-3内的气体通入储罐内。Specifically, taking the orientation of Figure 1 as a reference, one end of the outer sleeve 2-2 is fixedly installed in the storage tank, and one end of the inner sleeve 1-3 can move up and down relative to the storage tank and the outer sleeve 2-2. The bottom ends of the outer sleeve 2-2 and the inner sleeve 1-3 are both sealed. During operation, the second through hole 1-4 on the inner sleeve 1-3 is aligned with the first through hole 2-3 on the outer sleeve 2-2, so that the water flowing into the inner sleeve 1-3 is The gas flows into the storage tank.

当然,设置一个套筒也能完成除桥工作,但是由于套筒是直接插入粉体内的,导致套筒上的通孔直接与粉体接触,粉体容易将通孔堵住,使得气体无法通过通孔通入储罐内,从而导致除桥效果不佳。Of course, setting up a sleeve can also complete the bridge removal work, but because the sleeve is directly inserted into the powder, the through hole on the sleeve is in direct contact with the powder. The powder can easily block the through hole, making it impossible for gas to pass through. The through hole leads into the tank, resulting in poor bridge removal.

当然,进气口1-1的具体位置本文没有做任何限定。Of course, the specific location of the air inlet 1-1 is not limited in this article.

在上述实施例的基础上,作为进一步的优选,全部第一通孔2-3均匀地设于外套筒2-2的第一预设段,全部第二通孔1-4均匀地设于内套筒1-3底部的第二预设段,内套筒1-3带动所述第二预设段在所述第一预设段的范围内移动。On the basis of the above embodiment, as a further preference, all the first through holes 2-3 are evenly provided in the first preset section of the outer sleeve 2-2, and all the second through holes 1-4 are evenly provided in the first preset section of the outer sleeve 2-2. The second preset section at the bottom of the inner sleeve 1-3 drives the second preset section to move within the range of the first preset section.

具体地,上述的第一预设段以及第二预设段指的是外套筒2-2以及内套筒1-3上的某段位置。Specifically, the above-mentioned first preset section and second preset section refer to a certain section position on the outer sleeve 2-2 and the inner sleeve 1-3.

当内套筒1-3上下移动时,控制内套筒1-3的第二预设段始终在外套筒2-2的第一预设段范围内上下来回反复,以确保第二通孔1-4始终能够面向第一通孔2-3,以使气体始终能够依次通过进气口1-1、进气通道、第二通孔1-4以及第一通孔2-3流入至储罐内。When the inner sleeve 1-3 moves up and down, the second preset section of the inner sleeve 1-3 is controlled to always repeat up and down within the first preset section of the outer sleeve 2-2 to ensure that the second through hole 1-4 can always face the first through hole 2-3, so that the gas can always flow into the storage through the air inlet 1-1, the air inlet channel, the second through hole 1-4 and the first through hole 2-3. inside the tank.

另外,为了保证除桥的效果,将气体的流速控制在40-60m/s内。In addition, in order to ensure the bridge removal effect, the gas flow rate is controlled within 40-60m/s.

在上述实施例的基础上,作为进一步的优选,全部第一通孔2-3沿外套筒2-2的周向壁以及轴向均匀设置,且第一通孔2-3的孔径为3-20μm。On the basis of the above embodiment, as a further preference, all first through holes 2-3 are evenly arranged along the circumferential wall and axial direction of the outer sleeve 2-2, and the aperture of the first through holes 2-3 is 3-20 μm. .

具体地,外套筒2-2上段为环形套筒,下段为烧结金属。Specifically, the upper section of the outer sleeve 2-2 is an annular sleeve, and the lower section is sintered metal.

在上述实施例的基础上,作为进一步的优选,全部第二通孔1-4沿内套筒1-3的周向壁以及轴向均匀设置,且第二通孔1-4的孔径为1-3mm。On the basis of the above embodiment, as a further preference, all second through holes 1-4 are evenly arranged along the circumferential wall and axial direction of the inner sleeve 1-3, and the aperture of the second through holes 1-4 is 1-3 mm. .

也就是说,沿内套筒1-3的轴向间隔设置了多排第二通孔1-4,每排第二通孔1-4沿内套筒1-3的周向侧壁间隔设置。That is to say, multiple rows of second through holes 1-4 are provided at axial intervals along the inner sleeve 1-3, and each row of second through holes 1-4 is provided at intervals along the circumferential side wall of the inner sleeve 1-3. .

在上述实施例的基础上,作为进一步的优选,除桥套筒组件还包括密封腔2-1,连通外套筒2-2位于储罐外的一端,且密封连接内套筒1-3,密封腔2-1内设置有惰性气体,以防止粉体飘出。On the basis of the above embodiment, as a further preference, in addition to the bridge sleeve assembly, it also includes a sealed cavity 2-1, communicating with the outer sleeve 2-2 at one end outside the storage tank, and sealingly connected with the inner sleeve 1-3, An inert gas is provided in the sealed cavity 2-1 to prevent powder from floating out.

具体地,密封腔2-1与外套筒2-2一体式设置,也就是说,外套筒2-2位于储罐外的一端为密封腔2-1,且密封腔2-1的尺寸大于外套筒2-2的尺寸,内套筒1-3的一端依次穿入密封腔2-1以及外套筒2-2内,且将内套筒1-3与密封腔2-1的连接处进行密封,同时密封腔2-1背离储罐的一端设置有密封进气口2-4,通过该密封进气口2-4往密封腔2-1内通入惰性气体,从而起到密封作用。Specifically, the sealing chamber 2-1 and the outer sleeve 2-2 are provided integrally, that is to say, the end of the outer sleeve 2-2 located outside the storage tank is the sealing chamber 2-1, and the size of the sealing chamber 2-1 Larger than the size of the outer sleeve 2-2, one end of the inner sleeve 1-3 penetrates into the sealing cavity 2-1 and the outer sleeve 2-2 in sequence, and connects the inner sleeve 1-3 and the sealing cavity 2-1 The connection is sealed, and at the same time, a sealing air inlet 2-4 is provided at one end of the sealing cavity 2-1 away from the storage tank. Inert gas is introduced into the sealing cavity 2-1 through the sealing air inlet 2-4, thereby achieving the effect of Sealing effect.

进一步地,由于惰性气体的密度大于空气的密度,使得密封腔2-1内的压强大于储罐内的压强,此压强差就会把储罐内的粉体紧紧地密封住,以防止粉体上窜到密封腔2-1内。Furthermore, since the density of the inert gas is greater than the density of air, the pressure in the sealed cavity 2-1 is greater than the pressure in the storage tank. This pressure difference will tightly seal the powder in the storage tank to prevent the powder from leaking out. The body jumps into the sealed cavity 2-1.

当然,密封腔2-1与储罐之间的压差不能太大,不然会影响除桥的效率;也不能过小,不然密封效果不明显,以维持密封腔2-1与储罐内压差在5-7KPa即可。Of course, the pressure difference between the sealing chamber 2-1 and the storage tank cannot be too large, otherwise it will affect the efficiency of bridge removal; it cannot be too small, otherwise the sealing effect will not be obvious, so as to maintain the internal pressure between the sealing chamber 2-1 and the storage tank. The difference is only 5-7KPa.

在上述实施例的基础上,作为进一步的优选,除桥套筒组件还包括驱动件1-2,连接内套筒1-3伸出外套筒2-2的一端,用于驱动内套筒1-3沿外套筒2-2移动。On the basis of the above embodiment, as a further preference, in addition to the bridge sleeve assembly, it also includes a driving member 1-2, connected to one end of the inner sleeve 1-3 extending out of the outer sleeve 2-2, for driving the inner sleeve 1 -3 moves along the outer sleeve 2-2.

另外,驱动件1-2还可以耦接传感器,以控制内套筒1-3自动地上下移动,从而实现自动地除桥,提高了除桥效率。In addition, the driving member 1-2 can also be coupled to a sensor to control the inner sleeve 1-3 to automatically move up and down, thereby realizing automatic bridge removal and improving the efficiency of bridge removal.
